Abstract EN
This study tested the hypothesis that the easily degradable carbohydrates of the sugar beet silage (S) will improve the anaerobic digestion of grass silage (G) more profoundly compared to co-digestion of sugar beet silage with maize silage (M).
M : S and G : S mixtures were tested in two continuous laboratory-scale AD experiments at volatile solid ratios of 1 : 0, 6 : 1, 3 : 1, and 1 : 3 at organic loading rates of 1.5 kgVS m−3 day−1.
While the sugar beet effects in mixtures with maize silage were negligible, co-digestion with grass silage showed a beneficial performance.
There, the specific methane production rate was 0.27 lN kg−1VS h−1 at G : S ratio of 6 : 1 compared to G : S 1 : 0 with 0.14 lN kg−1VS h−1.
In comparison to G : S 1 : 0, about 44% and 62% higher biogas yields were obtained at G : S 6 : 1 and 3 : 1, respectively.
Also, the highest methane concentration was found in G : S at ratio of 1 : 3.
Synergistic increase of methane yield was found in co-digestion in both experiments, but higher effect was realized in G : S, independently of the amount of sugar beet silage.
The findings of this study emphasize the improvement of AD of grass silage by even low addition of sugar beet silage.
